Protect Your Investment.
Test early and test often.
A simple swab test performed at the right time could save you hundreds of thousands of dollars in lost product and the costs of remediation of a contaminated facility.
* The earlier you detect a contaminant, the less time it has to spread and affect your facility and your bottom line.
* You need to know about a problem before it appears on your official legal test results, potentially affecting your license.
* By the time you can visually see a problem with the naked eye, the problem is much more difficult and costly to fix.
* Testing frequency mandated by law is primarily intended to protect the end-consumer, not the grower or the manufacturer.
* The key to success is in being proactive, not reactive, and to formulate an assertive plan of action for monitoring your environment.
The scientists at GreenHill Laboratories, LLC have been performing professional environmental testing for food and dairy facilities for more than three decades, let us bring our experience to your team!

Meet Our Team

GreenHill Labs is a 2nd generation laboratory with over three decades of family experience in microbiological testing and analysis for the food, water, and dairy industry. Here is just a small sampling of the microscopy we have captured in our labs.

Owner and founder of GreenHill Laboratories, LLC, Hilary Glass has 15 yeas experience in food microbiology. She is a certified food, water and dairy analyst. Working mainly in dairy microbiology, she has assisted with the development of the first agar techniques and methods used to determine total mold counts, mold speciation, and various pathogens in raw cannabis and cannabis products. She has studied the microbiological and mycological cannabis production environments, and currently studies the bacteriological flora of cannabis and cannabis production facilities.
"We are dedicated to introducing marijuana producers and consumers to the microbial world to enable wise decisions and prevent the adversarial positions in which producers, consumers and government regulators often find themselves in."

Director of Analytical Chemistry, Ryan Randolph, joined GreenHill Laboratories in April, 2015. Ryan brings extensive knowledge and skills that he developed over 14 years of professional experience in analytical chemistry. Ryan earned a BS in Environmental Chemistry Department at University of Colorado, Colorado Springs in 2001. He went on to join a startup laboratory where he developed expertise developing and validating methods for determining pesticide residues in agricultural crops. After five years of pesticide testing, Ryan moved on to join Scynexis, Inc., a biotech in North Carolina, where he applied his skills in analytical chemistry to support discovery of new medicines. While in NC, Ryan earned a Master’s of Science in Clinical Research, graduating Summa Cum Laude from Campbell University in 2012. Over the course of his career, he has gained considerable experience in regulated laboratory environments where analytical methodology and documentation is required to meet rigorous Good Laboratory Practice (GLP) standards established by the EPA and FDA. Upon passage of Amendment 64, Ryan set his intention to return home to Colorado and become a leader in the emerging marijuana testing industry. Two years later, Ryan has validated a robust potency method for cannabis flower, concentrates and edibles. Ryan’s validation work was audited in October, 2015 by the Colorado Department of Health and Environment, who moved swiftly to recommend a potency certification for GreenHill Laboratories within nine business days. This extremely short turnaround time is a testament to the impeccable attention to detail Ryan applied to his method validation, which extends to all his endeavors. Ryan aims to ultimately utilize his skills in analytical chemistry and pharmaceutical research to help unlock the medicinal potential of this miraculous plant.

Laboratory Director Donald Salter has a BS in Bacteriology from the University of Alabama, an MS in Bacteriology from the University of Florida and a PhD in Biomedical Sciences from the University of Tennessee. Prior to obtaining his PhD, Salter was the military head of the Microbiology, Mycology, and Mycobacteriology Sections in the Department of Pathology at Valley Forge General Hospital in Pennsylvania during the Vietnam War. He has done post doctoral research in cancer biology and membrane biochemistry in the Department of Microbiology and Biochemistry at the University of Illinois, and immunology in the Department of Microbiology at Michigan State University. As a research microbiologist in the USDA-ARS Avian Disease and Oncology Laboratory in East Lansing, and then research assistant professor and consultant in the Department of Microbiology at Michigan State University, he was the lead researcher of a team that produced the first transgenic chicken as well as the first transgenic disease-resistant animal. He received a National Science Foundation Research Opportunity Award to do research in plant molecular and cell biology in the Department of Plant Biology at the University of Wisconsin in Madison in summer of 2004 and 2005. He retired in 2006 after a decade of teaching Microbiology (nursing and general), Biology, Cell Biology, Genetics, Biochemistry, Virology, Undergraduate and Graduate Research, Seminar, and associated laboratories in the Department of Biological and Environmental Sciences at the University of West Alabama. He has been a consultant in Leuther Laboratories since 2002 and has worked over seven years as a molecular biologist (half-time) in a small seed company.
